LARRY J. BUDD ill VIII] BY w L I L I' I I 22 F169 X X ATTORNEYS UnitedStates Patent Filed Get. 3, 1962, Ser. No. 2281174 11 Claims. (Cl. 229-14) The present invention relates generally to a cushioning pad forinsertion into a carton for end engagement with an article to bedisposed in the carton. This invention further relates to a method formanufacturing the cushioning pad.

In an exemplary application of this invention, a television receiverincluding a cabinet and receiver apparatus therewithin, underlying thecabinet to support the cabinet bottom wall is spaced in relation to thecontainer bottom as shown in the US. Patent N 0. 2,895,661. Thecushioning pad is adapted to be disposed over the cabinet top andcarries means depending therefrom for engaging upper portions of thefront wall, rear walls and side walls of the cabinet to support the samein spaced relation to the vertical walls of the container and also toprotect the edges of the cabinet at the inner sections of the top wallwith the front wall, rear wall and side wall.

The cushioning pads herein disclosed are improvements upon thecushioning pad disclosed in my aforesaid patent whereby the instantcushioning pads can be more readily manufactured at a reduced cost. Theinstant cushioning pads are sturdier and stronger than the cushioningpad disclosed in my aforesaid patent according to important features ofthis invention. To attain this end, a paperboard plate is secured withina central pocket of the pad and which pad is peripherally defined byrectangularly arranged, reinforced cushioning tubes. The outer edges ofthe paperboard plate are engaged in edgewise reinforcing relationagainst the rectangularly arranged tubes for maintaining the tubes in anupright position relative to the central portion of the cushioning pad.In order to further reinforce the cushioning pad, side tubes areprovided with inside side walls having notched areas which are engagedagainst inside and bottom side walls of the rear .tube and with bottomwalls of the side tubes being secured in lapped engagement with a bottomwall of the rear tube.

There are two types of cushioning pads disclosed herein, one of which isparticularly adapted for being mounted on a television apparatus and theother of which is suited for being mounted on a stereo cabinet. It willbe appreciated that the television tube extends rearwardly of thetelevision cabinet and this tube must be protected by the cushioningpad. Since a stereo cabinet does not have a television tube, the frontand rear tubes on the pad may be manufactured identical to one another.

It is an important object of this invention to provide a new andimproved cushioning pad which may be more easily manufactured at areduced cost.

Still another object of this invention is to provide a new and improvedcushioning pad which is sturdier than similar pads previously used.

Yet another object of this invention is to provide a new and improvedmethod for manufacturing the cushioning pads described above.

A still further object of this invention is to provide a new andimproved cushioning pad having a central plate with its peripheral edgesbutt engaged with the inside walls of the tubes disposed on one Side ofthe pad and further with the plate edges serving to hold the insideWalls in engagement with the reinforcing means disposed within thetubes.

Still another feature of this invention relates to a new and improvedmethod of securing a paperboard plate with ice a cushioning pad to holdrectangularly arranged reinforcing tubes in upright position on the pad.Other objects and features of this invention will more fully becomeapparent in view of the following detailed description taken inconjunction with the accompanying drawings illustrating severalembodiments and in which:

FIGURE 9 is a bottom view of a modified type of cushioning pad; and

FIGURE 10 is a fragmentary end view of the pad as viewed on the line X-Xlooking in .the direction indicated by the arrows as shown in FIGURE 9.

In FIGURE 8 the reference numeral 7 indicates a paperboard carton 7having a television receiver 8 mounted therein and with a cushioning pador cushioned packing insert E mounted on top of the receiver 8 forprotecting the receiver within the carton 7 during shipment. Thecushioning pad 9 in FIGURE 8 and the cushioning pad 9' in FIGURE 9 andthe methods of making the same embody the inventive concepts presentedherein.

In general, each of the cushioning pads may be formal from relativelyrig-id form-sustaining sheet material and preferably for an inexpensiveexpendable material such as paperboard, fiberboard or the like. The padsare formed by making bends at score lines which may be scored by markingthe blank or preferably by actual indentation of the blank, especiallywhen the blank is of paperboard or a like material, but it will beappreciated that marking or indentation is not necessarily required andthe terms scoring and score line are therefore used in a figurativesense to indicate the position of the bends.

The cushioning pad 9 is formed by cutting, scoring and folding acushioning pad blank or sheet 10 in the manner hereafter described. Theblank 10 includes a central pad portion or area 11 having four blank orsheet margins 12, 13, 14 and 15. The sheet margin 12 is scored alongscore lines 16, 1'7 and 18 to provide flaps or sections 19, 20 and 21.The flap 17 is provided with a notch area 22 having a configurationapproximating the peripheral dimension of the rear tubular disclosurehereafter described. The sections 19, 20 and 21 are folded at the scorelines 16, 17 and 18 about a reinforcing insert 23 to form a reinforcedside tube or tubular enclosure 24. The packing may be comprised of anysuitable material such as layers of corrugated paper with thecorrugations eXtend ing transversely of the tube 24. Other suitabletypes of reinforcing inserts may be used, if desired.

The margin 13 is scored with score lines being indicated 39. Areinforcing insert 31 which is substantially identical to the insert 23is adapted to be disposed interiorly within reinforced rear tube ortubular enclosure 32 upon folding the tube sections 28, 29 and 30 at thescore lines 25, 26 and 27 about the insert 31.

The margin 14 is scored as indicated by score lines 34, 35 and 36 toform tube sections 37, 38 and 39. The tube section 39 is provided with anotch area 40 of the same type as the notch area 22 for snug engagementwith tube flaps or sections 29 and 30 on the tube 24. The margin 14 isadapted to be folded along the score lines to turn the tube sections 37,38 and 39 about a reinforcing insert 41 to form a reinforced side tubeor tubular enclosure 42.

The fourth margin 15 is provided with a T-shaped notch area 44 providinga pair of pad blanks with the first pad blank being scored as indicatedby score lines 45, 46 and 47 to form pad sections 48, 49 and 50. Thesepad sections are folded about a reinforcing insert or filler 51 to forma reinforced front tube 52. The other pad blank is scored along scorelines 54, 55 and 56 to form pad sections 57, 58 and 59. These padsections are folded about a reinforcing insert 60 to form a reinforcedfront tube 61.

As the reinforced tubes 24, 32, 42, 52 and 61 are formed, thereinforcing inserts are preferably glued by a suitable glue such as avegetable base glue with the sur rounding flaps as well as the centralpad portion or area 11 for holding the tubes in a plane generally normalto the plane of the central pad portion 11. In order to further rigidifythe tubes 24, 32 and 42, the tube flaps or sections 20 and 38 on theside tubes 24 and 42 are glued to the flap or section 29 on the reartube 32. Still further, in order to rigidify the juncture between thetube 24 and 52 and the juncture between the tubes 52 and 61, the flapsor sections 21 and 50 are glued together and the flaps or sections 39and 59 are glued together as shown in FIGURE 3.

In view of the foregoing it will be appreciated how the cushioning pad 9can be formed from a reduced amount of material and yet be of a veryrigid construction. In order to further rigidify the pad 9, andaccording to still further important features of this invention, apaperboard reinforcing plate 63 is pressed against the central padportion or area 11 and preferably secured thereto by means of glue orthe like in such manner that its marginal edges 64, 65, 66 and 67 areengaged with the inner side walls defined by the flaps or sections 21,3t), and 39 as well as against the tubes 52 and 61. The plate 63 is cutto a dimension which corresponds precisely to the dimension of the topof the television receiver 8. By securing the plate 63 with the pad 9 inthe manner described, the tubes 24, 32, 42, 52 and 61 are all reinforcedas a result of the engagement of the marginal edges of the plate 63therewith. The marginal edge 67 engages with end edges of the tubes 52and 61 rather than with the side walls of the tubes and it will beappreciated that such engagement serves to rigidify the pad 9 to betterenable the pad to resist forces tending to displace the tubes withrespect to the central pad portion or area 11.

Shown in FIGURES 9 and is the modified cushioning pad 9. This pad 9 isidentical to the pad 9 except that the tubes 52 and 61 found on the pad9 are replaced by a reinforced side tube or tubular enclosure 32" whichis identical to reinforced side tube or tubular enclosure 32'. The tube32' is identical to the tube 32 previously described in connection withthe pad 9. In order to further rigidify the pad 9, opposite ends of sidetubes 20' and 42 are notched as indicated at 22-22 and 4040' to enablethe tube side walls to be fitted about rear and 'front tubes 32' and 32"for reinforced engagement therewith. It will thus be appreciated thatthe opposite ends of the tubes 20 and 42 are engaged in fitted relationin glued assembly with rear and front tubes 32' and 32" in contrast tothe pad 9 where the tubes 20 and 42 were only notched at one end forengagement with the rear tube 32.

The pad 9 is adapted for use with a conventional cabinet whereas the pad9 is adapted for assembly with a television receiver cabinet 9. In thisregard, the tubes 52 and 58 are adapted to extend rearwardly of thetelevision receiver cabinet 8 to protect the television tube whichextends rearwardly behind the television receiver cabinet on mostconventional types of television receiver sets.

It will be understood that modifications and variations may be effectedwithout departing from the scope of the novel concepts of the presentinvention.
